ScrOG netting is a trellis system designed to spread your cannabis canopy flat, giving every bud site equal access to light. This set from Royal Queen Seeds covers 120 x 120cm, comes with securing clips and support poles, and sets up in minutes — no DIY bodging required. If you've been meaning to buy a screen of green kit but keep putting it off, this is the one that removes every excuse.
The ScrOG netting set comes in two variants based on the diameter of your tent or frame poles. Measure before you order — it takes ten seconds and saves you a return.
| Variant | Pole diameter | Best for |
|---|---|---|
| 15–18mm | 15–18mm poles | Most lightweight grow tents and thinner steel frames |
| 19–22mm | 19–22mm poles | Heavy-duty tents and thicker aluminium or steel frames |
Not sure? Grab a tape measure or vernier caliper and wrap it around one of your tent poles. If you're between sizes, go with the larger variant — a slightly loose clip is easier to work with than one that won't close.
A ScrOG net increases usable bud sites by physically forcing the canopy into a flat, even plane instead of the default Christmas-tree shape. Without training, one dominant cola at the top hogs the light while the lower branches produce airy, underdeveloped buds. You end up with one decent nug and a load of larfy popcorn. We've seen it hundreds of times, and it's the single biggest waste of potential in a home grow.
As branches grow upward through the netting, you weave them horizontally through the next hole along. According to a 2025 article in PMC, this practice enhances light penetration and airflow, and prevents a dominant central cola from shading out the rest of the plant. A 2023 EMCDDA technical report on indoor cultivation efficiency noted that canopy-management techniques like ScrOG can improve light utilisation by up to 40% compared to untrained plants. The result: more bud sites receiving direct light, which translates to heavier, denser harvests from the same number of plants and the same wattage.
The honest limitation? ScrOG adds a bit of hands-on time during veg and early flower. You'll be checking your net every couple of days, tucking branches, and making decisions about which shoots to keep and which to prune. It's not a set-and-forget method. But if you're growing in a tent and you want to squeeze genuine performance out of your setup, it's one of the best returns on effort you'll get. We'd pick ScrOG over just topping alone every single time — the canopy uniformity is night and day.
The ScrOG netting kit contains one 120 x 120cm net, securing clips sized to your chosen pole variant, and support poles — everything you need to get started with zero additional purchases.

Complete your ScrOG setup: pair this netting with a solid grow tent — the Dark Box 120 x 120 x 200cm is the obvious match for full-coverage canopy training. You'll also want sharp, clean pruning scissors for the lower growth you'll be removing beneath the net. For monitoring your environment, consider adding a thermo-hygrometer to keep temperature and humidity dialled in across that flat canopy.
Setup takes roughly 10–15 minutes from unboxing to a fully tensioned net ready for training — here's the step-by-step process.
The most common mistake we see at the Azarius counter is setting the net too high — roughly 8 out of 10 first-timers place it at 50cm or more above the pots. If your net is 50cm up, the branches have already developed vertical dominance before they hit the mesh, and you're fighting the plant instead of guiding it. Keep it at 20–30cm and let the weaving do the work. The netting in this kit has a mesh opening of approximately 10 x 10cm — large enough to get your fingers through comfortably for tucking, small enough to actually hold a branch in place. It feels like a proper growing tool, not a repurposed football net.
One thing to watch: once you've woven branches into the net, moving your plants becomes a two-person job (or a disaster). Get your pots in their final position before you start training. We've had customers message us mid-grow asking how to relocate a fully ScrOG'd plant. The answer is: you don't. Plan ahead. We had one regular who tried to slide a 15-litre pot sideways after two weeks of weaving — snapped three branches and lost about 25% of his canopy. He ordered a second ScrOG netting set the next day and started the replacement grow with the pots bolted in place. Lesson learned the expensive way.
ScrOG netting produces the most uniform canopy of any home-grow training method, outperforming LST ties and topping alone in light distribution across the full grow area. LST with ties and stakes gives you more flexibility to move plants around, but you'll never get as uniform a canopy as a proper screen — in side-by-side comparisons, ScrOG setups typically yield 20–30% more per square metre than LST-only grows under the same 600W light, according to grower data compiled by community forums over the 2022–2024 period. Topping alone creates more colas but doesn't address the light distribution problem — you still end up with a bushy plant where the inner branches get shaded out. ScrOG combines both: you top your plants first (usually at the 5th or 6th node), then use the net to spread the resulting 4–8 branches into a flat, even canopy. It's the best approach for maximising yield per square metre in a tent, full stop. If you want to buy one piece of training equipment and nothing else, make it a ScrOG net.
Screen of Green. It's a cannabis training technique where you use a horizontal net to spread the canopy flat, giving all bud sites equal light exposure. The "screen" is the netting itself.
Yes. After harvest, cut the branches free, clean the net, and store it flat. The clips and netting hold up across several cycles — most growers get 4–6 runs before the clips need replacing. Just inspect the clips for cracks before each new run.
By forcing branches horizontal, every bud site sits at the same distance from your light. No single cola dominates and shades the rest. More even light means more even bud development and heavier total harvests from the same wattage.
Once your topped plants have branches reaching about 5cm above the netting — typically late veg. Keep weaving through the first 2–3 weeks of flower until 60–70% of the net is filled, then let them grow upward.
Absolutely. The net is trimmable — just cut along a row of holes with scissors to match your tent footprint. Works fine in 80 x 80cm or 100 x 100cm spaces.
Strongly recommended. Without topping, one main stem dominates. Topping creates multiple branches that you then spread across the net. ScrOG and topping work as a pair — one without the other gives you half the benefit.
Around 20–30cm above the top of your pots. Lower than you'd think. This lets you start weaving branches early while they're still flexible and easy to guide.
